Diskimage-builder tools for creation cloud images

Steps how to create cloud image with Apache Hadoop installed using diskimage-builder project:

  1. Clone the repository "https://github.com/openstack/diskimage-builder" locally. Note: Make sure you have commit 43b96d91 in your clone, it provides a mapping for default-jre.
git clone https://github.com/openstack/diskimage-builder
  1. Add ~/diskimage-builder/bin/ directory to your path (for example, PATH=$PATH:/home/$USER/diskimage-builder/bin/ ).
  2. Export the following variable ELEMENTS_PATH=/home/$USER/diskimage-builder/elements/ to your .bashrc. Then source it.
  3. Copy file "img-build-sudoers" from ~/disk-image-builder/sudoers.d/ to your /etc/sudoers.d/.
chmod 440 /etc/sudoers.d/img-build-sudoers
chown root:root /etc/sudoers.d/img-build-sudoers
  1. Export savanna-elements commit id variable (from savanna-extra directory):
export SAVANNA_ELEMENTS_COMMIT_ID=`git show --format=%H | head -1`
  1. Move elements/ directory to disk-image-builder/elements/
mv elements/*  /path_to_disk_image_builder/diskimage-builder/elements/
  1. Export DIB commit id variable (from DIB directory):
export DIB_COMMIT_ID=`git show --format=%H | head -1`
  1. Call the following command to create cloud image is able to run on OpenStack:

8.1. Ubuntu cloud image

JAVA_FILE=jdk-7u21-linux-x64.tar.gz DIB_HADOOP_VERSION=1.2.1 OOZIE_FILE=oozie-4.0.0.tar.gz disk-image-create base vm hadoop oozie ubuntu root-passwd -o ubuntu_hadoop_1_2_1

8.2. Fedora cloud image

JAVA_FILE=jdk-7u21-linux-x64.tar.gz DIB_HADOOP_VERSION=1.2.1 OOZIE_FILE=oozie-4.0.0.tar.gz DIB_IMAGE_SIZE=10 disk-image-create base vm fedora hadoop root-passwd oozie -o fedora_hadoop_1_2_1

Note: If you are building this image from Ubuntu or Fedora 18 OS host, you should add element 'selinux-permissive'.

JAVA_FILE=jdk-7u21-linux-x64.tar.gz DIB_HADOOP_VERSION=1.2.1 OOZIE_FILE=oozie-4.0.0.tar.gz DIB_IMAGE_SIZE=10 disk-image-create base vm fedora hadoop root-passwd oozie selinux-permissive -o fedora_hadoop_1_2_1

In this command 'DIB_HADOOP_VERSION' parameter is version of hadoop needs to be installed. You can use 'JAVA_DOWNLOAD_URL' parameter to specify download link for JDK (tarball or bin). 'DIB_IMAGE_SIZE' is parameter that specifes a volume of hard disk of instance. You need to specify it because Fedora doesn't use all available volume. If you have already downloaded the jdk package, move it to "elements/hadoop/install.d/" and use its filename as 'JAVA_FILE' parameter. In order of working EDP components with Savanna DIB images you need pre-installed Oozie libs. Use OOZIE_DOWNLOAD_URL to specify link to Oozie archive (tar.gz). For example we have built Oozie libs here: http://savanna-files.mirantis.com/oozie-4.0.0.tar.gz If you have already downloaded archive, move it to "elements/oozie/install.d/" and use its filename as 'OOZIE_FILE' parameter.
